This definitely has potential to be a great game, but the game often did not register my hits, forcing my to try other moves (even then, it didn't always work). Also, there was a bug where once I got to the part where the 10 tails was confined, it didn't let me go right enough to face the fat thing. Although the game does not have "incredible art", it is still nice to look at. I love the variety of moves you put into this, but try including the rasengan as well or at least as a finisher. Please keep developing this and getting better. Had this game have been more polished (the bugs worked out, more responsive hit boxes, something to let you know when your health is going down beside the health bar, and sound affects among other things), this could be an awesome game worthy of an award (at least in my opinion).
By the way, I'd suggest adding the arrow keys as the moving controls as well.
